Faithful slaves

Did the “worthless slave” know the story of the foolish bridesmaids? When they did not preserve the oil for their lamps, the women were locked out of the party. We could understand why, if the slave knew that story, he would focus on preserving his money. But now he is locked out while the bridesmaids cry until their mascara runs, and all gnash their teeth. We’re left to wonder, “Just what do you do in an apocalypse?”
